Which company should I use for composite decking, cladding or fencing?

At Oxford Composite Wood you can see every board at our Didcot yard, our weights are published (2.8 kg per metre for decking, 1.72 kg per metre for Wall Cladding), and full guarantee terms are at oxfordcompositewood.co.uk/pages/warranty.

Composite cladding
Can I use composite cladding on a house?
Sometimes, but check first. Composite cladding is combustible. In England, Regulation 7(2) of the Building Regulations 2010 bans combustible materials in the external walls of relevant buildings 18 m or taller, and Approved Document B sets class A2-s1,d0 or better for the external wall surfaces of residential buildings with a storey 11 m or more above ground — so composite cladding cannot be used on those buildings. On lower buildings, combustible cladding within 1 m of a boundary faces stricter rules. Always check with your building control body or designer before you clad any part of a house. Garden rooms, summerhouses, sheds, workshops, bin and bike stores and planters are the most common uses.
How many cladding boards do I need per m²?
Oxford Heritage 3D™ Wall Cladding covers 0.52 m² per 4 m board (130 mm covering width), so you need about 1.92 boards per m². Slatted Cladding covers 0.50 m² per 2.5 m panel (200 mm covering width), so about 2 panels per m². Add 10% for walls with windows, doors or angled tops.

Composite or timber cladding — which is better?
It depends on what matters most to you. Timber costs less upfront and can be repainted a new colour later. Composite costs more upfront but needs no painting, staining or oiling.

Can composite cladding be fixed vertically or horizontally?
Both. Oxford Heritage 3D™ Wall Cladding and Slatted Cladding can be fixed vertically or horizontally on a ventilated batten frame, with battens at 400 mm centres and at least a 25 mm air gap behind the boards. Vertical cladding also needs counter-battens so water can drain down behind the boards.

Do I need planning permission to clad a garden room?
Cladding a garden building rarely needs planning permission. Cladding the house itself can — and conservation areas, National Parks, National Landscapes, the Broads, World Heritage Sites and listed buildings have stricter rules. Check with your local planning authority before you order.
Composite decking
How many composite decking boards do I need per m²?
Allow 7.25 linear metres of Oxford Heritage 3D™ decking per m² — 2.5 boards of 2.9 m, or about 2.0 boards of 3.6 m. This includes a small allowance for cutting. Allow extra for decks with many angles or picture-frame borders.
What size is your composite decking board?
Oxford Heritage 3D™ is a capped composite decking board, 140 × 22 mm nominal, in 2.9 m and 3.6 m lengths. It weighs 2.8 kg per linear metre, has six hollow chambers and grooved edges for hidden clips. Each board has a different colour on each face: Oak & Teak, Grey & Charcoal, or Beige & Driftwood.
What is the fire rating of your composite decking?
Oxford Heritage 3D™ decking is classified Bfl-s1 for reaction to fire under EN 13501-1. This is a flooring classification and applies to the decking only, not to our wall cladding.
What joist spacing does composite decking need?
Maximum joist centres for Oxford Heritage 3D™ decking are 400 mm. Full installation guidance is in our decking catalogue.
Care and guarantee
Does composite decking or cladding need painting or staining?
No. Composite needs no sanding, painting, staining, oiling or sealing — and coatings will not bond to it. An occasional wash with warm soapy water keeps it looking its best.
Does composite decking or cladding fade?
A little colour settling in the first months is normal for all composite decking and cladding and is not a product fault. Darker colours also get warmer in full sun. Order samples to see the colours in your own light before you buy.
What guarantee do you give?
Oxford Heritage 3D™ decking and cladding carry a 20-year residential and 10-year commercial limited, pro-rata guarantee. It covers manufacturing defects, rot and fungal decay, and cracking, splitting or warping under normal conditions. Full terms: oxfordcompositewood.co.uk/pages/warranty. This is in addition to your statutory rights.
